Immune Checkpoint Inhibitors for Microsatellite Instability High Unresectable Obstructive Colon Cancer: A Report of Two Cases.
Article in Surgical case reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionPatients with obstructive colon cancer (OCC) with distant metastases often present with a poor general condition, including malnutrition, anemia, and systemic inflammation. Traditionally, these patients undergo stoma creation and/or primary tumor resection followed by systemic chemotherapy. However, for patients with DNA mismatch repair-deficient/microsatellite instability high (dMMR/MSI-H) colorectal cancer, the emergence of immune checkpoint inhibitors (ICIs) has revolutionized treatment strategies, with remarkable antitumor effects. We report two cases of successful management of MSI-H OCC, achieving curative resection while avoiding decompressive procedures, including colostomy creation. CASE PRESENTATION:
conclusionsThis report highlights the potential benefits of ICI treatment for dMMR/MSI-H OCC, particularly for rapid relief of obstruction-related symptoms and facilitating oncologically safe R0 resection. In cases of MSI-H OCC, ICIs can be highly effective as an alternative to traditional decompression procedures.
